Unknown. It would only make sense if the same grammar files could be fed to each. I have no idea whether that's true or not. If not, Greg's idea is worth researching.
PCCTS 1.x grammar files tend to have lots of C code interwoven in them -- at least for tricky, ill-defined grammars like BibTeX. ;-)
ANTLR 2.x grammars certainly allow Java code to be woven into them; I assume you can instead weave C++ or Sather if that's your preference. Obviously, this would be one problem with having a common grammar for JPython and CPython.
